摘要
龙潭河特大桥采用连续刚构体系,其桥墩最高达178 m。为了分析桥墩及桩基础对桥梁结构的受力影响,建立考虑桩基作用及墩底固结两个不同的计算模型,计算和比较了箱梁施工预拱度及温度荷载作用下的结构控制截面的弯矩。
Longtan River Bridge is designed as a continuous rigid-frame bridge with its highest pier up to 178 m. In order to analyze the force influence of the bridge pier and the pile foundation on the bridge structure,this article establishes two different computation models of considering pile foundation action and with fixity at the base of pier, analyzing and comparing the box beam construction camber and the bending moments of structure control sections under temperature loading of both models.
